FIDES-WinTUBE-3D Tunneling construction

Interactive Graphical Preprocessing for Tunneling and Geotechnical Models for SOFiSTiK Solvers

FIDES-WinTUBE-2D/3D has been initially developed as a specialized tool for tunneling. It includes a lot of wizards to assist the user to define and carry out very easy tunneling-specific tasks. However the functionality of WinTUBE is universal enough to become the tool of choice for many general FE-analysis. Especially if 3D volume models should be analysed and/or successive construction stages need to be simulated.

The integrated SOFiSTiK-interface generates mesh- and calculation-control files and starts the SOFiSTiK-calculation. These ASCII files needn’t, but could be edited manually. In addition to the detailed and illustrated technical report generated directly by WinTUBE-2D/3D, the SOFiSTiK kernel will be requested to generate a file containing a set of plots and numerical results. Additional all SOFiSTiK postprocessing tools may be used at any time.
